Now, let us find the area of a semicircle when the diameter is given. A Norman window has the shape of a semicircle atop a rectangle so that the diameter of the semicircle is equal to the width of the rectangle. Find the given derivative by finding the first few derivatives and observing the pattern that occurs. Suppose that 430 ft of fencing is used to enclose a corral in the shape of a rectangle with a semicircle whose diameter is a side of the rectangle. This is one of the reasons why the second form is a little more convenient.
